JOHN D. BRETT, OF CORDELE, GEORGIAI AXLE JOURNAL AND HUB.

Specification of Application filed. December 1 To all whom it may concern:

Be it known that 1, JOHN D. BRETT, a citizen of the United States, r siding at (lordele, in the county of Crisp, State of Georgia, have invented certain new and useful improvements in Axle Journals and Hubs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art'to which it appertains to make and use the same.

This invention relates to improvements in axle journals and vehicle hubs, and has for one of its objects to improve the construetion and increase the efiiciency and utility of devices of this character.

Another object of the invention is to provide a simply constructed device wherein the introduction of the lubricating material is facilitated and the journal and hub less, liable to run dry The invention further consists in certain novel features of construction, as hereafter shown and described and then specifically pointed out in the claims, and in the drawings illustrating the preferred embodiment of the invention, Figure 1 is a plan view of the hub and a portion of the axle with the improvement applied. Fig. 2 is a longitudinal sectional elevation of the parts shown in Fig. 1. Fig. 3 is a transverse sec tion on the line '3-3 of Fig. .2. Fig. 4 is a perspective view of the outer sand band ofthe hub detached with the improved attachment for applying .the lubricating material to the outer portion of the hub.

The improved device may be applied without material structural changes to axles of various sizes, and to axles employed upon various kinds of vehicles, and it is not desired therefore to limit the invention to any specific form of. axle or to axles employed forany specific form of vehicle.

For the purpose of illustration the improvement is shown applied to a conventional axle, a portion of which is represented at 10 and provided with a ournal 11 having a reduced outerthreaded end 12. The hub of the vehicle is represented at 13 and provided with an internal box 14:, the box being shorter than the internal bore of the hub, as shown. The inner end of the hub is provided with a sand band 15 extending rearwardly over the adjacent portion of the axle, as shown.

Bearing around the outer end of the hub Letters Patent. Patented May 1 1, 1909.

is a holding band 16, and bearing-over this holding band is an outer sand band 17, the latter extending beyond the outer end of the hub and over the holding nut.

Bearing within the inner end of the hub is a sleeve 18, and formed with a reduced end hearing within the adjacent portion of the box 14, the sleeve having an external flange 19 bearing against the rear or inner end of the hub.

Bearing around the journal 11 next to the axle stock .10 is a sleeve 20, this sleeve extending between the sleeve 18 and the journal as shown, and provided with a lateral flange 21 extending between the flange 19 and the adjacent portion of the axle.

Passing through the outer end of the axle 10 adjacent to the flange 21 and likewise extending through the same is a feed pipe 22 through which lubricating material is fed to the journal, the inner end of the tube 22 discharging against the flanges 1921 and thence between the sleeves 18-20 and so jinto the space between the journal and the box 14 and thus lubricate the journal.

Supported within the outer end of the hub 13 is'a sleeve 23 having a reduced inner fend and extending within the outer end of the box let, and likewise provided with a flange 24 bearing against the outer end of the hub.

Mounted upon the journal. 11 Within the sleeve 23 is another sleeve 25 having an external flange 26 hearing againstthe outer face of the flange 24.

, The flange 26 is provided with two spaced lugs 27-28, and fitting over the other terminal 12 of the journal is the holding nut 29, the nut having cavities to receive the studs 2728, and thus eflectually prevent the sleeve 25 and its flange 26 from running Qbaclrwardly off from the journal.

' The holding nut 29 is provided with a threaded aperture in its outer face in which threaded stud '30 is inserted, the stud provided "with a screw driver cavity whereby it may be adjusted through the outer end of the sand band 17 By turning the screw in one direction the movement of the nut 29 may be controlled to prevent lost motion or 'looseness, and by rotating the screw still further the nut may be firmly locked in position.

Formed in the exterior of the outer sand band ,17 are two pairs of slots 3132 spaced apart, and formed through the sand band near the slots 32 is a cavity 33, through which oil may be inserted around the flanges and percolates between these flanges and thence to the journal as hereafter explained.

Slidably disposed over the outer surface of the band 17 is a relatively short plate 3 1 having lugs 35 extending through the slots Z- i-? 2 and adapted to be clenched beneath thenn to couple the plate FA- to the band 17, and permit it to move circumferentially of the band for a distance equal to the range of the slots.

Connected to the plate 31'- by a rivet or other suitable fastening means is a relatively long plate 37, the latter having an aperture 38 adapted to register with the aperture 33 when the plates ti t- 57 are disposed in one position and to be located 01 posite the solid or unperforated portion of the band when the nlates are disoosed in another position.

When the plates are adjusted with the lugs at one end the slots 3132 the aperture 38 will be opposite the solid portion of the band and then when the plates are adjusted with the lugs at the opposite end of the slots the aperture will. register with the apertu "e 88. When the apertures are thus in registering position it will be obvious that the discharge nozzle of an oil can can be inseted to apply lubricating material to the joint between the flanges 2 t26, and thus supply lubricating material to the journal, as the oil will percolate behind the flange and find its way into the cavity be tween the journal and the box. Thus the lubricating material may be readily applied at both ends of the journal 11.

The lugs 2l -o8 operating in the cavities in the holding nut 29 and the oil pipe 22 serve to hold the sleeves Pal-20 from rotating, and thus confine the friction between the sleeves 2318 and the sleeves The improved device is simple in construction, can be inexpensively manufactured. and produces a very efficient axle and hub which may be readily lubricated without removal from the journal.

Vl hat is claimed is:--

1. The combination with an axle and its journal. the journal having a threaded terminal, of a hub having an internal box or" less length than the hub, a sleeve within the hub at each or .7 and extending into the box and with flanges bearing against the ends of the hub, a sleeve bearing over the ournal at each end and within said hub engaging sleev s and with flanges b airing against the flanges of the same. and a holding nutcngaging the threaded end of the journal and bearing against the flange of the adjacent journal sleeve.

The con'ibination with journal. the journal having a threaded terminal, of a hub havin an internal box of less length than the hub. a sleeve within the hub at ach end and extending into the box and with flanges bearing against the ends of the hub. a sleeve bearing over the jouraal at Gnk'll end and within. said hub engaging sleeves and with flanges bearing against th angeroi? the same. :he flange of the l ee'-.'e ha ing spaced lugs. and a holding nut en;;' the threaded end of. the journal and Lear-rig against the flange an axle and its of the adjacent journal sle/eve and provided with iavities to receive lugs.

3. The combination with an axle and its journal. the journal having a thraded terminal. of a hub h: vine; an internal box of less length than the hub, with a sand band at the outer end thereof and provided with a transverse oil u erture. a shield carried by the band and movable orr said oil aperture. a sleeve within the hub at each end and extending into the box and with flanges bearing over the journals at :h rnd and within the said hub engz 'ing sleev s and with flanges bearing against the flanges of the san'ie, and a holding .int eng z aging the threaded end of the journal and bearing against the flange of the adjzu-ent journal sleeve.
